The present invention will be described in detail with reference to the accompanying drawings and examples.

The utility model provides a high-efficient diffusion equipment, as shown in figure 1, include: the device comprises a mounting base 1 for mounting on a chimney, a plurality of flue gas diffusion pipelines 2 for diffusing flue gas in the chimney and a turbulence assembly 3; the flue gas diffusion pipeline 2 is arranged on the mounting base 1; the turbulence component 3 is arranged at the outer side of all the smoke diffusion pipelines 2, and an air diffusion channel 4 for the air outside the chimney to enter is reserved between the turbulence component and each smoke diffusion pipeline 2.

In practical application, the mounting base 1, the flue gas diffusion pipeline 2 and the turbulence component 3 are all made of metal; installation base 1 sets up at chimney top opening part, if pour at chimney top opening part through cement, get into in the flue gas diffusion pipeline 2 from chimney top exhaust flue gas, because bernoulli's effect, make air on every side get into air diffusion channel 4 from the below of vortex subassembly 3, and rise along with the flue gas together, the dilution of flue gas is accelerated, reduce the influence of discharging the flue gas to the surrounding environment, be particularly useful for the laboratory, the pig farm, the compost field, reach standard foul waste gas after handling such as food processing workshop, the flue gas is exactly through handling up to standard foul waste gas, better to the effect that reduces factory floor foul concentration.

Further, as shown in fig. 1, the spoiler assembly 3 includes: a flow disturbing ring 31 and a support plate 32 corresponding to the plurality of flue gas diffusion pipelines 2; one end of each support plate 32 is fixedly connected with the outer wall of the corresponding smoke diffusion pipeline 2, and the other end of each support plate is fixedly connected with the inner wall of the turbulent flow ring 31.

Specifically, the number of the flue gas diffusion pipes 2 in the present application is 4, and in other embodiments, the number of the flue gas diffusion pipes 2 may be increased or decreased according to the diameter of the chimney; through the setting of vortex ring 31 and a plurality of and the setting of extension board 32 for vortex ring 31 covers and establishes outside all flue gas diffusion pipeline 2, and that is air diffusion channel 4 encircles flue gas diffusion pipeline 2, and when the flue gas of chimney passes through flue gas diffusion pipeline 2 and discharges, thereby produce the bernoulli effect, and the central gas flow makes central atmospheric pressure be less than ambient atmospheric pressure, thereby makes outside air orderly follow vortex ring 31's below get into air diffusion channel 4 and rise to, does benefit to the mixture of outside air and flue gas.

Further, as shown in fig. 2, the inner diameter of the turbulent flow ring 31 is gradually reduced from bottom to top, and the inner diameter of the turbulent flow ring 31 is gradually reduced from bottom to top to guide the air in the air diffusion channel 4 to gradually approach the flue gas in the rising process, so that the mixing effect of the air and the flue gas is further enhanced, and the dilution effect of the air on the flue gas is ensured.
